The ED50 as determined by the dose-dependent proliferation of mouse BALB/c 3T3 cells, is less than 0.04 ng/ml corresponding to a Specific Activity of 25MIU/mg.

Lyophilized at a concentration of 1 mg/ml in 5mM NaP, pH-7.5, 50mM NaCl.

Sterile Filtered White lyophilized (freeze-dried) powder.

Greater than 98.0% as determined by:
(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.

It is recommended to reconstitute the lyophilized Fibroblast Growth Factor-acidic in sterile 18MΩ-cm H₂O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.

Escherichia Coli.

Lyophilized Fibroblast Growth Factor-1 although stable at room temperature for 3 weeks, should be stored desiccated below -18^oC. Upon reconstitution FGF-a should be stored at 4^oC between 2-7 days and for future use below -18^oC.
Please prevent freeze-thaw cycles.
